SPECIFICATION forming part of Letters Patent No. 770,205, datedSeptember 13, 1904.

Application filed January 27, 1904. Serial No. 190,886- (No model.)

To all whom, it may concern.-

Be it knownthat I, ALVIN O. WARRnN,a citi- Zen of the United States,residing at Allendale, in the county of Providence and State of RhodeIsland, have invented a certain new and'usefu'l Improvement inDetachable Foot- Rests, of which the following is a specification.

The object of my invention is to provide an improved foot-rest for theuse of linemen in climbing the wooden poles which support theline-wires; and it consists in the improved construction of thefoot-rest and the baseplate by means of which it is connected to thepole.

In the accompanying drawings, Figure 1 represents a side View of thebase-plate and the connected foot-rest. Fig. 2 represents a front viewof the base-plate. Fig. 3 represents a side View of the foot-rest. Fig.4: represents a top view of the foot-rest and base-plate. Fig. 5represents a detail section taken in the line 00 w of Fig. 1. Fig. 6represents a section taken in the line 1 y of Fig. 8.

In the drawings, Arepresents the foot-rest, and B the base-plate whichis to be attached to the pole. The plate'B is provided at its lowerportion with the projecting dovetailed groove (0 and at the upperportion with the dovetailed groove &, which is recessed back from thelower dovetailed groove a, as shown in Figs. 2 and 4, and between thedovetailed grooves a and b is located the shoulder a.

The foot-rest A is provided with the dovetailed projections g g, whichserve to engage with the dovetailed grooves a and b of the base-plate,and thus firmly lock the parts together, and the employment of the twodovetailed grooves a and b in the base-plate serves to support andsteady the inserted foot-rest. The downward movement of the foot-rest islimited by the shoulders f and f of the footrest, which engage with theshoulders and 0 of the base-plate.

I claim as my invention- 1. The combination of the base-plate arrangedto be permanently secured to a pole and provided with a doubledovetailed groove, and the detachable foot-rest having an end arrangedto enter and interlock with said dovetailed groove, the same serving asa lateral guide for the foot-rest, substantially as described.

2. The combination of the base-plate arranged to be permanently securedto a pole and provided with a double dovetailed groove, the foot-restarranged with a double dovetailed end to interlock with said base-plate,substantially as described.

3. The combination of the base-plate having a projecting dovetailedgroove and the recessed dovetailed groove, the shoulder between the twodovetailed grooves with the foot-rest engaging therewith, substantiallyas described.
